Chapter 14 Configuring Resilient Packet Ring on the ML-Series Card

Configuring RPR

Creating the Bridge Group and Assigning the Ethernet and SPR Interfaces

The default behavior of the ML-Series cards is that no traffic is bridged over the RPR even with the interfaces enabled. This is in contrast to many Layer 2 switches, including the Cisco Catalyst 6500 and the Cisco Catalyst 7600, which forward VLAN 1 by default. The ML-Series card will not forward any traffic by default, including untagged or VLAN 1 tagged packets.

For any RPR traffic to be bridged on an ML-Series card, a bridge group needs to be created for that traffic. Bridge groups maintain the bridging and forwarding between the interfaces on the ML-Series card and are locally significant. Interfaces not participating in a bridge group cannot forward bridged traffic.

To create a bridge group for RPR, you determine which Ethernet interfaces need to be in the same bridge group, create the bridge group, and associate these interfaces with the bridge group. Then associate the SPR interface with the same bridge group to provide transport across the RPR infrastructure.

Figure 14-6illustrates a bridge group spanning the ML-Series card interfaces, including the SPR virtual interface of RPR.

Caution

All Layer 2 network redundant links (loops) in the connecting network, except the RPR topology, must

 

 

be removed for correct RPR operation. Or if loops exist, you must configure STP/RSTP.

 

 

 

 

 

 

 

To configure the needed interfaces, perform the following procedure, beginning in global configuration

 

 

mode:

 

 

 

 

 

 

 

 

 

 

 

 

Command

Purpose

 

Step 1

 

 

 

 

Router(config)# interface type number

Enters interface configuration mode for the Ethernet

 

 

 

interface joining the bridge group.

 

Step 2

 

 

 

 

Router(config-if)# no shutdown

Enables the interface.

 

Step 3

 

 

 

 

Router(config-if)# bridge-group

Creates the specified bridge group and assigns the bridge

 

 

bridge-group-number

group to the interface. Creating the bridge from the

 

 

 

interface configuration disables STP or RSTP

 

 

 

(spanning-disabled), which is recommended for RPR.

 

Step 4

 

 

 

 

Router(config)# interface spr1

Enters interface configuration mode for the SPR

 

Step 5

 

 

 

 

Router(config-subif)# bridge-group

Associates the SPR interface to the specified bridge

 

 

bridge-group-number

group.

15310-CL, 15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
